• Breaking up a large PHP object used to abstract the database. Best practices?

  - by John Kershaw

  Two years ago it was thought a single object with functions such as $database->get_user_from_id($ID) would be a good idea. The functions return objects (not arrays), and the front-end code never worries about the database. This was great, until we started growing the database. There's now 30+ tables, and around 150 functions in the database object. It's getting impractical and unmanageable and I'm going to be breaking it up. What is a good solution to this problem? The project is large, so there's a limit to the extent I can change things. My current plan is to extend the current object for each table, then have the database object contain these. So, the above example would turn into (assume "user" is a table) $database->user->get_user_from_id($ID). Instead of one large file, we would have a file for every table.

• Dual usage of asp.net mvc and php under same domain

  - by jim

  Hello all, I've got a scenario where we have a customer who has a linux hosted php app (joomla) that they wish to integrate with some back-end asp.net mvc functionality that was created for a 'sister' site. Basically, the mvc site has prices and stock availability methods which (in the sister site) populates dropdown lists and other 'order' style info on the pages. I've been tasked with looking at the integration options to allow the php site to use this info as a 'service'. (as ever, these guys are looking at cost of ownership, maintenence etc, so this is their preferred route) Has anyone done anything similar with success?? I'd imagine (much like the sister site) liberal doses of ajax will be employed in order to populate portions of the page on demand. So this may have a bearing on any suggestions that you may have. Also, the methods that are being called ultimately end up populating the same database, so there are no issues with correlating the ID's across the different platforms. I don't really want to go down any 'iframe' type route if at all possible, tho' reality may dictate this as being an option. I'm possibly (naively) imagining that i could simply invoke the mvc functions directly from the php app with some sort of 'session' variable being passed for authentication. pretty tall order or pretty straightfwd?? cheers jim

• Call Python From PHP And Get Return Code

  - by seaboy

  Hello everyone, I am calling a python script from PHP. The python program has to return some value according to the arguments passed to it. Here is a sample python program, which will give you a basic idea of what i am doing currently: #!/usr/bin/python import sys #get the arguments passed argList = sys.argv #Not enough arguments. Exit with a value of 1. if len(argList) < 3: #Return with a value of 1. sys.exit(1) arg1 = argList[1] arg2 = argList[2] #Check arguments. Exit with the appropriate value. if len(arg1) > 255: #Exit with a value of 4. sys.exit(4) if len(arg2) < 2: #Exit with a value of 8. sys.exit(8) #Do further coding using the arguments------ #If program works successfully, exit with a value of 0 As you can see from the above code, my basic aim is for the python program to return some values (0,1,4,8 etc) depending on the arguments. And then the calling PHP program to access these returned values and do the appropriate operation. Currently i have used "sys.exit(n)", for that purpose. Am i right in using sys.exit, or do I need to use something else? And also what method exists in PHP so that I can access the return code from python? Sorry for the long question, but hopefully it will help in you understanding my dilemma Thanks a ton

• PHP in Wordpress Posts - Is this okay?

  - by Thomas

  I've been working with some long lists of information and I've come up with a good way to post it in various formats on my wordpress blog posts. I installed the exec-PHP plugin, which allows you to run php in posts. I then created a new table (NEWTABLE) in my wordpress database and filled that table with names, scores, and other stuff. I was then able to use some pretty simple code to display the information in a wordpress post. Below is an example, but you could really do whatever you wanted. My question is - is there a problem with doing this? with security? or memory? I could just type out all the information in each post, but this is really much nicer. Any thoughts are appreciated. <?php $theResult = mysql_query("SELECT * FROM NEWTABLE WHERE Score < 100 ORDER BY LastName"); while($row = mysql_fetch_array($theResult)) { echo $row['FirstName']; echo " " . $row['LastName']; echo " " . $row['Score']; echo "<br />"; } ?>

• PHP Installer Script

  - by totallymike

  I'm looking to create a fully functional installer for a slightly complicated web application using PHP. Basically, you go to URL/setup.php and you are asked a series of questions, and during the process a database is set up and a config file is populated according to the answers given. A good example of this is how Wordpress handles its install procedure, as well as any number of PHP applications. My question to you, oh great internet, is this: This technique is so prevalent that surely not everyone is re-inventing the wheel, is there a place I can go to find a basic walkthrough (not code, just a description) of the technique. Either that or a good book which outlines if not this specific technique, then the fundamentals relevant to this? I can bang out something ugly and probably make it work myself, but if there's a best known method I'd like to find it. Far more important than having a working function is to have a description of what's going on from step to step. I'd like to have the installer, but I really want to learn how it's done. Thanks, Mike

• Storing array as value in associative array

  - by Jagannath

  i have a problem where I need to have an array as value in associative array. Go through the code below. Here I am trying to loop the files in a directory and it is more likely that more than 1 file can have the same ctrno. So, I would like to see what are all the files having the same ctrno. The code below gives error at "$ctrno_hash[$ctrno] = @arr;" in the else condition. The same case would be for if condition as well. Am I following the right approach or could it be done diffently? sub loop_through_files { $file = "@_"; open(INPFILE, "$file") or die $!; #print "$file:$ctrno\n"; while (<INPFILE>) { $line .= $_; } if ($line =~ /$ctrno/ ) { print "found\n"; if ( exists $ctrno_hash[$ctrno]) { local @arr = $ctrno_hash[$ctrno]; push (@arr, $file); $ctrno_hash[$ctrno] = @arr; } else { local @arr; push(@arr, $file); $ctrno_hash[$ctrno] = @arr; } } }

• PHP Missing Function In Older Version

  - by Umair Ashraf

  My this PHP function converts a datetime string into more readable way to represent passed date and time. This is working perfect in PHP version 5.3.0 but on the server side it is PHP version 5.2.17 which lacks this function. Is there a way I can fix this efficiently? This is not only a function which needs this "diff" function but there are many more. public function ago($dt1) { $interval = date_create('now')->diff(date_create($dt1)); $suffix = ($interval->invert ? ' ago' : '-'); if ($v = $interval->y >= 1) return $this->pluralize($interval->y, 'year') . $suffix; if ($v = $interval->m >= 1) return $this->pluralize($interval->m, 'month') . $suffix; if ($v = $interval->d >= 1) return $this->pluralize($interval->d, 'day') . $suffix; if ($v = $interval->h >= 1) return $this->pluralize($interval->h, 'hour') . $suffix; if ($v = $interval->i >= 1) return $this->pluralize($interval->i, 'minute') . $suffix; return $this->pluralize($interval->s, 'second') . $suffix; }

• Custom Template and Layered Navigation

  - by russjman

  I created a custom template for the category view that displays all subcategories for current category. When i set the current category as is_anchor = yes in the admin, the layered navigation filters show up in the side bar. The Sub categories is one of the filters are there as well, but when i click on one them the page still displays all subcategories. I would like to some how test for active filters in my custom template, which i assume there has to be a way to get this info from Magento. Below is my custom code. $_filters is how i am trying to access these filters, but it gives me nothing. Am i invoking this incorrectly, from the wrong place, in the wrong context? <?php $_helper = $this->helper('catalog/output'); $_filters = $this->getActiveFilters(); echo $_filters; if (!Mage::registry('current_category')) return ?> <?php $_categories=$this->getCurrentChildCategories() ?> <?php $_count = is_array($_categories)?count($_categories):$_categories->count(); ?> <?php if($_count): ?> <?php foreach ($_categories as $_category): ?> <?php if($_category->getIsActive()): ?> <?php $cur_category=Mage::getModel('catalog/category')->load($_category->getId()); $layer = Mage::getSingleton('catalog/layer'); $layer->setCurrentCategory($cur_category); $_imgHtml = ''; if ($_imgUrl = $this->getCurrentCategory()->getImageUrl()) { $_imgHtml = '<img src="'.$_imgUrl.'" alt="'.$this->htmlEscape($_category->getName()).'" title="'.$this->htmlEscape($_category->getName()).'" class="category-image" />'; $_imgHtml = $_helper->categoryAttribute($_category, $_imgHtml, 'image'); } echo $_category->getImageUrl(); ?> <div class="category-image-box"> <div class="category-description clearfix" > <div class="category-description-textbox" > <h2><span><?php echo $this->htmlEscape($_category->getName()) ?></span></h2> <p><?php echo $this->getCurrentCategory()->getDescription() ?></p> </div> <a href="<?php echo $this->getCategoryUrl($_category) ?>" class="collection-link<?php if ($this->isCategoryActive($_category)): ?> active<?php endif ?>" >See Entire Collection</a> <a href="<?php echo $this->getCategoryUrl($_category) ?>"><?php if($_imgUrl): ?><?php echo $_imgHtml ?><?php else: ?><img src="/store/skin/frontend/default/patio_theme/images/category-photo.jpg" class="category-image" alt="collection" /><?php endif; ?></a> </div> <?php echo '<pre>'.print_r($_category->getData()).'</pre>';?> </div> <?php endif; ?> <?php endforeach ?> <?php endif; ?>

• Parse text file on click and display

  - by John R

  I am thinking of a methodology for rapid retrieval of code snippets. I imagine an HTML table with a setup like this: one two ... ten one oneTwo() oneTen() two twoOne() twoTen() ... ten tenOne() tenTwo() When a user clicks a function in this HTML table, a snippet of code is shown in another div tag or perhaps a popup window (I'm open to different solutions). I want to maintain only one PHP file named utitlities.php that contains a class called 'util'. This file & class will hold all the functions referenced in the above table (it is also used on various projects and is functional code). A key idea is that I do not want to update the HTML documentation everytime I write/update a new function in utilities.php. I should be able to click a function in the table and have PHP open the utilities file, parse out the apropriate function and display it in an HTML window. Questions: 1) I will be coding this in PHP and JavaScript but am wondering if similar scripts are available (for all or part) so I don't reinvent the wheel. 2) Quick & easy Ajax suggestions appreciated too (probably will use jquery, but am rusty). 3) Methodology for parsing out the functions from the utilities.php file (I'm not to good with regex).

• Switching languajes on a website with PHP

  - by jnkrois

  Hello everybody, I'm just looking for some advice. I'm creating a website that offers (at least) 2 languages. The way I'm setting it up is by using XML files for the language, PHP to retrieve the values in the XML nodes. Say you have any XML file, being loaded as follows: <?php $lang = "en"; $xmlFile = simplexml_load_file("$lang/main.xml"); ?> Once the file contents are available, I just output each node into an HTML tag like so: <li><?php echo $xmlFile->navigation->home; ?></li> which in turn is equal to : <li><a href="#">Home</a></li> as a nav bar link. Now, the way in which I'm switching languages is by changing the value of the "$lang" variable, through a "$_POST", like so: if(isset($_POST['es'])){ $lang = "es"; }elseif(isset($_POST['en'])){ $lang = "en"; } The value of the "$lang" variable is reset and the new file is loaded, loading as well all the new nodes from the new XML file, hence changing the language. I'm just wondering if there is another way to reset the "$lang" variable using something else, other than "$_POST" or "$_GET". I don't want to use query string either. I know I could use JavaScript or jQuery to achieve this, but I'd like to make the site not too dependable on JavaScript. I'd appreciate any ideas or advice. Thanks

• Struts2 Converting Enum Array fills array with single null value

  - by Kyle Partridge

  For a simple action class with these member variables: ... private TestConverterEnum test; private TestConverterEnum[] tests; private List<TestConverterEnum> tList; ... And a simple enum: public enum TestConverterEnum { A, B, C; } Using the default struts2 enum conversion, when I send the request like so: TestConterter.action?test=&tests=&tList=&b=asdf For test I get a null value, which is expected. For the Array and List, however, I get and Array (or list) with one null element. Is this what is expected? Is there a way to prevent this. We recently upgraded our struts2 version, and we had our own converters, which also don't work in this case, so I was hoping to use the default conversion method. We already have code that is validating these arrays for null and length, and I don't want to have to add another condition to these branches. Is there a way to prevent this bevavior?

• Special characters stripped by mySQL/PHP JSON

  - by Will Gill

  Hi, I have a simple PHP script to extract data from a mySQL database and encode it as JSON. The problem is that special characters (for example German ä or ß characters) are stripped from the JSON response. Everything after the first special character for any single field is just stripped. The fields are set to utf8_bin, and in phpMyAdmin the characters display correctly. The PHP script looks like this: <?php header("Content-type: application/json; charset=utf-8"); $con = mysql_connect('database', 'username', 'password'); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("sql01_5789willgil", $con); $sql="SELECT * FROM weightevent"; $result = mysql_query($sql); $row = mysql_fetch_array($result); $events = array(); while($row = mysql_fetch_array($result)) { $eventid = $row['eventid']; $userid = $row['userid']; $weight = $row['weight']; $sins = $row['sins']; $gooddeeds = $row['gooddeeds']; $date = $row['date']; $event = array("eventid"=>$eventid, "userid"=>$userid, "weight"=>$weight, "sins"=>$sins, "gooddeeds"=>$gooddeeds, "date"=>$date); array_push($events, $event); } $myJSON = json_encode($events); echo $myJSON; mysql_close($con); ?> Sample output: [{"eventid":"2","userid":"1","weight":"70.1","sins":"Weihnachtspl","gooddeeds":"situps! lots and lots of situps!","date":"2011-01-02"},{"eventid":"3","userid":"2","weight":"69.9","sins":"A second helping of pasta...","gooddeeds":"I ate lots of salad","date":"2011-01-01"}] -- in the first record the value for field 'sins' should be "Weihnachtsplätzchen". thanks very much!

• PHP MySQL Weird Update Problem

  - by Tim

  I have a heap based table in MySQL that I am trying to update via PHP, but for some reason, the updates do not seem to be taking place. Here is my test code: <?php $freepoints[] = 1; $freepoints[] = 2; $freepoints[] = 3; foreach ($freepoints as $entrypoint) { $query = "update gates set lane='{$entrypoint}' where traffic > 50 limit 50"; echo "$query\n"; mysql_query($query); echo mysql_affected_rows()."\n"; } ?> This outputs the following: update gates set lane='1' where traffic > 50 limit 50 50 update gates set lane='2' where traffic > 50 limit 50 50 update gates set lane='3' where traffic > 50 limit 50 50 In the database to start with lanes 1/2/3 had 0 records and lanes 4/5/6 had 100 records. From this I am expecting all 6 lanes to now have 50 records each. However when I look lanes 4/5/6 still have 100 records and 1/2/3 still have 0 records. When I copy the query "update gates set lane='1' where traffic 50 limit 50" into phpMyAdmin it works absolutely fine, so any ideas why it isn't working in my PHP script when mysql_affected_rows is saying it has updated 50 records?

• How should I write new code when the old codebase and the environment uses lots of globals in PHP

  - by Nicola Peluchetti

  I'm working in the Wordpress environment which itself heavily relies on globals and the codebase I'm maintaining introduces some more. I want this to change and so I'm trying to think how should I handle this. For the globals our code has introduced I think I will set them as dependencies in the constructor or in getter / setter so that I don't rely on them being globals and then refactor the old codebase little by little so that we have no globals. With Wordpress globals I was thinking to wrap all WP globals inside a Wrapper class and hide them in there. Like this class WpGlobals { public static function getDb() { global $wpdb; return $wpdb; } } Would this be of any help? The idea is that I centralize all globals in one class and do not scatter them through the code, so that if Wordpress kills one of them I need to modify code only in one place. What would you do?

• Using PHP and cURL to login to indyarocks.com

  - by Divya

  I am new to cURL and don't know much about it. I basically want to login to my account on www.indyarocks.com through libcurl for PHP. I don't know what type of authentication it uses (I don't know how to find that out.). When I go to http://www.indyarocks.com, I get a login form which asks for my username and password. I put in my username and password and click login and everything is good. I tried to automate this using cURL. This is a snippet of my code. curl_setopt($curl_connection, CURLOPT_URL, "http://www.indyarocks.com/loginchk.php"); curl_setopt($curl_connection, CURLOPT_POST, 1); curl_setopt($curl_connection, CURLOPT_HTTPAUTH, CURLAUTH_ANY); curl_setopt($curl_connection, CURLOPT_USERPWD, $username.':'.$password); I looked at the source of the login page and found out the address of the page to which the username and password are sent (the action attribute of the form) which is "http://www.indyarocks.com/loginchk.php" and set it as the target url. When I run this, I get username or password is wrong error and the login fails. My username and password is correct. I don't know what the problem is. Can the password be encrypted? Can that be responsible for this failure? Please help me get around this problem. I'll be really thankful. Thanks in advance.

• translate a PHP $string using google translator API

  - by Toni Michel Caubet

  hey there! been google'ing for a while how is the best way to translate with google translator in PHP, found very different ways converting URLS, or using Js but i want to do it only with php (or with a very simple solution JS/JQUery) example: //hopefully with $from_lan and $to_lan being like 'en','de', .. or similar function translate($from_lan, $to_lan, $text){ // do return $translated_text; } can you give me a clue? or maybe you already have this function.. my intention it's to use it only for the languages i have not already defined (or keys i haven't defined), that's why i wan it so simple, will be only temporal.. EDIT thanks for your replies we are now trying this soulutions: function auto_translate($from_lan, $to_lan, $text){ // do $json = json_decode(file_get_contents('https://ajax.googleapis.com/ajax/services/language/translate?v=1.0&q=' . urlencode($text) . '&langpair=' . $from_lan . '|' . $to_lan)); $translated_text = $json->responseData->translatedText; return $translated_text; } (there was a extra 'g' on variables for lang... anyway) it returns: works now :) i don't really understand much the function, so any idea why is not acepting the object? (now i do) OR: unction auto_translate($from_lan, $to_lan, $text){ // do // $json = json_decode(file_get_contents('https://ajax.googleapis.com/ajax/services/language/translate?v=1.0&q=' . urlencode($text) . '&langpair=' . $from_lan . '|' . $to_lan)); // $translated_text = $json['responseData']['translatedText']; error_reporting(1); require_once('GTranslate.php'); try{ $gt = new Gtranslate(); $translated_text = $gt-english_to_german($text); } catch (GTranslateException $ge) { $translated_text= $ge->getMessage(); } return $translated_text; } And this one looks great but it doesn't even gives me an error, the page won't load (error_report(1) :S) thanks in advance!

How can I get the original name of the file (I'm more interested in the original extension) The important things here are: The url actually redirects to image so i cant get it from original url the final url does not have the file name in headers

• OpenGL - Rendering from part of an index and vertex array depending on an element count

  - by user1423893

  I'm currently drawing my shapes as lines by using a VAO and then assigning the dynamic vertices and indices each frame. // Bind VAO glBindVertexArray(m_vao); // Update the vertex buffer with the new data (Copy data into the vertex buffer object) glBufferData(GL_ARRAY_BUFFER, numVertices * sizeof(VertexPosition), m_vertices.data(), GL_DYNAMIC_DRAW); // Update the index buffer with the new data (Copy data into the index buffer object) glBufferData(GL_ELEMENT_ARRAY_BUFFER, numIndices * sizeof(unsigned short), indices.data(), GL_DYNAMIC_DRAW); glDrawElements(GL_LINES, numIndices, GL_UNSIGNED_SHORT, BUFFER_OFFSET(0)); // Unbind VAO glBindVertexArray(0); What I would like to do is draw the lines using only part of the data stored in the index and vertex buffer objects. The vertex buffer has its vertices set from an array of defined maximum size: std::array<VertexPosition, maxVertices> m_vertices; The index buffer has its elements set from an array of defined maximum size: std::array<unsigned short, maxIndices> indices = { 0 }; A running total is kept of the number of vertices and indices needed for each draw call numVertices numIndices Can I not specify that the buffer data contain the entire array and only read from part of it when drawing? For example using the vertex buffer object glBufferData(GL_ARRAY_BUFFER, numVertices * sizeof(VertexPosition), m_vertices.data(), GL_DYNAMIC_DRAW); m_vertices.data() = Entire array is stored numVertices * sizeof(VertexPosition) = Amount of data to read from the entire array Is this not the correct way to approach this? I do not wish to use std::vector if possible.

  I'm trying to retrieve data in a javascript file from a php file using json. $items = array(); while($r = mysql_fetch_array($result)) { $rows = array( "id_locale" => $r['id_locale'], "latitudine" => $r['lat'], "longitudine" => $r['lng'] ); array_push($items, array("item" => $rows)); } ECHO json_encode($items); and in the javascript file I try to recover the data using an ajax call: $.ajax({ type:"POST", url:"Locali.php", success:function(data){ alert("1"); //var obj = jQuery.parseJSON(idata); var json = JSON.parse(data); alert("2"); for (var i=0; i<json.length; i++) { point = new google.maps.LatLng(json[i].item.latitudine,json[i].item.longitudine); alert(point); } } }) The first alert is printed, the latter does not, it gives me error: Unexpected token <.... but I do not understand what it is. Anyone have any idea where am I wrong? I also tried to recover the data with jquery but with no positive results.
